Watch Halsey & Charli XCX Cover the Spice Girls

It’s tough to imagine the contemporary pop landscape without the Spice Girls: Their influence reaches far and wide among stylish, irreverent female acts with a passion for “girl power.” During her Lollapalooza set, Charli XCX brought Halsey to the stage and the pair performed the Spice Girls’ breakout single “Wannabe.”

Last year marked the 20th anniversary of the Girls’ debut album Spice and a long-rumored reunion never materialized. The best thing about 20-year reunions is that 25-year reunions are just around the corner…maybe the Spice Girls can settle their differences and get it together by 2021.
